On Netflix US all six shorts that make up this OVA are smooshed into one episode. These are not plot-advancing stories, but rather ways to explore the Dorohedoro world and its characters in a lighthearted way. The most disappointing thing about the OVA is that it isn't fully animated. I'm sure the cost for fully animating something like this is pretty high compared to the possible return on investment, so I can't say they made a bad decision, but it is distracting that these shorts are, essentially, a parade of still images. About half the shorts feel like they give some tangible texture to the world andits characters—the one featuring Nikaidou and how she got started in her restaurant especially stands out—while the other half are cute little concepts that are fun for their five-or-so minute duration and then leave the mind (Ebisu trying to get her photo taken).
It's very disposable, even with the world/character texture, but for those who've watched through the first season, it's a nice little treat to wind down with, hence the fairly good score for something that is otherwise basically meaningless.
